Accomplishes every mission not covered by the commercial airlines or military
What is General Aviation
Add more seats on airplanes.
Negotiate for better prices on fuel and equipment.
Use smaller airplanes on less popular routes.
strategies commercial airlines use to maximize profit
Aviation deals with all aircraft within Earth’s atmosphere.
True
What is the difference between a UAV and a UAS?
A UAV is one component of a UAS
The purpose of military aviation is to _______.
defend the nation and its interests
What is one reason law enforcement uses general aviation aircraft?
To assist law enforcement officers on the ground with suspect apprehension
Among other things, space exploration seeks to determine if other planets have _______.
Water
Current space exploration research includes studying Earth.
True
Fly at or below 400 feet
Do not fly over people
Keep within visual line of sight
safety guidelines for flying unmanned aerial vehicles
What does the camber of an airfoil refer to?
The curve of the wing
Leonardo da Vinci’s flying machine, the ornithopter, was an invention that ____.
flapped its wings like a bird
why wind tunnels are used in testing the design of aircraft
To test scale models of airfoils and aircraft
The purpose of the burner of a hot air balloon is to warm passengers?
False
a contribution Greek myths made to civilization today
Inspiration for human flight
Birds generate ___(2 things)____ by flapping their wings.
lift and thrust
Hot air balloons rise because warm air in the balloon _______, lifting the balloon.
becomes less dense
Which type of aircraft performs best with a symmetrical airfoil?
Aerobatic aircraft
They approached problems systematically and methodically, controlling all other variables.
the Wright Brothers
Two things that best illustrates the mechanics of flying a hot air balloon
Density, buoyancy
Why is air density important when using hot air balloons?
As air inside the balloon gets warmer, the density of the air in the balloon decreases, causing it to rise.
For modern day gliders, what does Bernoulli’s Principle demonstrate?
Air moves faster over the top of the wing than air moving below the wing. This creates an area of low pressure on top of the wing, which lifts the glider up.
When the four forces of flight are balanced, the flying object is said to have ________.
equilibrium
Movement of a wing through the air creates _______ on the top of the wing as compared to the bottom of the wing, allowing for lift.
lower pressure
